 ## [Unreleased]
 
+### Changed
+- **Studio Vercel deployment — switched from InMemoryDriver to TursoDriver** — The Studio serverless
+  API entrypoint (`apps/studio/api/index.ts`) now uses `@objectstack/driver-turso` (TursoDriver)
+  instead of `@objectstack/driver-memory` (InMemoryDriver) for Vercel deployments. In production,
+  the driver connects to a Turso cloud database via `TURSO_DATABASE_URL` and `TURSO_AUTH_TOKEN`
+  environment variables (remote mode). For local development without those variables, it falls back
+  to `:memory:` (ephemeral SQLite). This ensures data persistence across serverless function
+  invocations on Vercel. The browser MSW mock kernel remains unchanged (InMemoryDriver).
+
 ### Added
 - **`@objectstack/driver-turso` — dual transport architecture** — TursoDriver now supports three
   transport modes: `local`, `replica`, and `remote`. Remote mode (`url: 'libsql://...'`) enables
